Here I write in simple word on LTE KPI Measurement Methodology and its Acceptance Procedure. As it’s for only at network start up stage and now a day worldwide so many operator starts to launch LTE and so this is the way for them to check of KPI in LTE LTE KPI Measurement Methodology The … Read more
Codeword, layer, and precoding in LTE Terms codeword, layer, and precoding have been taken to refer specifically to LTE signals and processing. The figure shows the processing steps to which they relate. The terms used in the following ways: Codeword: codeword represents the user data before it is formatted for transmission. One or two code … Read more
Threre are four Different Methods to Combine OFDMA for handle Multiuser System. Plain OFDM: Normal LTE OFDM has no built-in multiple-access mechanism. This is suitable for broadcast systems like DVB-T/H which transmit only broadcast and multicast signals and do not really need an uplink feedback channel (although such systems exist too). Packet Statistical Multiplexing: It … Read more
When we talk about LTE RF Planning then the one question in mind is that what about MIMO gains. Here I write Different Gain in LTE like MIMO Gains and Gains which brought by multiple antenna technology and By MIMO Like Power Combine Gain, Array Gain, Space Diversity Gain, Interference reduction gain and Spatial multiplexing … Read more
Here I write on simple how guard band requirement for LTE for 2 option. Guard band requirement LTE verses GSM and guard band requirement LTE FDD verse LTE TDD Guard Band Requirement: LTE-FDD vs GSM/UMTS Configuration is simpler for FDD based systems because both LTE FDD and its neighboring technologies are based on frequency duplex … Read more
Here I write another two step in LTE planning and why its require to know. Starting from MIMO and Beam Forming Implementation and Understanding of Current Transmission Backhaul Network Capability of operator MIMO and Beam Forming Implementation The number of antenna deployed per cell will have an immediate impact on the coverage and capacity offered … Read more
